thus described the invention, what as new is.

- 1;. Aroad drag including a frame-comprising? two end beams, twomain'beams be- '35 tween the. end-beams,- an angle brace attached to theforward. end portion of one of theend beams and to the rear end portionof one of the main beams, an angle brace attached to the forward endportion of the other one'ofthe end'beams and to the rear end portion ofthe other one of the main beams, and a platform extending across thetops of the main beams and secured to the end beams, with a plurality ofblades connected to the beams;

2. A road drag including a frame comprising two end beams and two mainbeams between the end beams, each end beam having a plurality ofv armspivoted thereto, a pinrality of blades each attached to a plurality ofthe arms, an' arm pivoted to the two-main ver and pivoted also to thearm that is piv-l ote'd to the main beams, a curved latch bar beams andattached to one of the blades, a lever pivoted to. the two main beamsand attached to another one of the blades, a coupling rod pivoted at oneend thereof to the leattached to the two main beams, and a latch mountedon the lever to engage the latch bar.

8. Aroad drag including two end beams having each an angle braceattached thereto osition,,being designed toiengage'eith'er linflatwise'between th'e ver and said arms extending up beyond the beams, aplurality of blades one of which is attached to a plurality of the armsand an- "other one of which is attached to the lever and also to aplurality of the arms, a coupling rod pivoted to the lever and also tothe arm that is pivoted to the two main beams, said rod bein arranged ina plane above the main beams, a coupling rod connected to an arm "of oneof the blades and also to an arm' of another one of the blades above theplane ofthe beams, a coupling rod connected to an-. other. arm of one ofthe blades'and also to an: other arm of another one of the blades abovethe plane of the beams, and a draft chain connected with the two endbeams.

4. In a road drag, the combination of a frame comprising a plurality ofmain beams, a plurality of end beams that are longer than the mainbeams, an angle brace attached to the forward end of one of the endbeams and to the rear end of one of" the main beams, an angle braceattached to the forward end of the other end beam, and to the rear endof the other main beam, and a platform extending across the middleportions of the plurality of beams and secured thereto, with draftlinksconnected to the forward ends of the end beams near the angle braces,and blades connected with the beams.

5. In a road drag, the combination. of a plurality of end beams havingeach a draft rod connected thereto, a chain connected to the draft rods,a each a flange at the top thereof and each flange having a plurality ofarms secured thereto, one of the flanges having a lever secured theretothat has a latch thereon, a plurality of main beams, a pivot connectingthe lever to the main'beams, pivots connecting one of the arms to themain beams, pivots connecting the remaining arms to the end beams,coupling rods connecting one of the arms with the lever, coupling rodsconnecting the remaining arms of one blade with the arms of anotherblade, and a latch bar secured to the main beams to be engaged by thelatch.
